Hi guys I have an ABS fault & Which is fault code (00283 left front ABS wheel speed sensor) after testing the left front sensor (showing no voltage) I checked the right hand front & there is no voltage from that either, Could someone enlighten me into what other faults would cause there to be no reading on either side. Also does anyone know where I could get replacement sensor with part number 4Z7 927 803 B as this has been discontinued by Audi since 2021 I believe, or is there an alternative with maybe a different part number? TIA Melv.
